There is no Italy- Switzerland pass, and you are not in Switzerland long enough to justify any of the passes offered. You can look for a discount fare from Spiez to Milan on either SBB or Trenitalia, and from Milan to La Spezia on Trenitalia. Their is no benefit to a night train between Florence and Rome ( if there even is one), as the trip is under two hours. Again, buy a discounted ticket on Trenitalia for the best price ( as low as 19 euro for the fast train).

Day 3: Train from Lauterbrunnen to Spiez, evening train from Spiez to La Speiza, Italy Dan, I'm a bit concerned for your third day. It is a very long journey from the Berner Oberland to the Cinque Terre. Both places are somewhat remote so connecting them can be somewhat circuitous. Connecting them will take all afternoon and evening. It can't be done in an evening. The last train that would work reasonably leaves Spiez at 2:36pm, 1436. Arrive at Brig and layover for 33 minutes. The train for Milano leaves at 1544, a EuroCity so reservations are mandatory. Arrival at Milano at 1735. Time for grab a takeaway dinner in the 30 minutes between trains. Depart Milano Centrale on an InterCity train, so mandatory reservations required, at 1805. If you are staying in the villages you can get off in Monterosso at 2102, or you stay on one more stop to LaSpezia at 2118. The last train leaving Lauterbrunnen, 6 minute connection in Interlaken Ost (pick up your feet) and 15 minutes at Spiez would be the 1333.

Day 6: rome local trains if any The only local Rome train you might take is the train to Ostia Antica from Station Ostiense / Piramide. You would be unlikely to do that because you will be in Napoli and I might guess that you might visit Pompeii or Herculaneum while there instead of Ostia Antica. With only one day in Rome I would have thought you would have your hands full.

Day 5: Night train from Florence to Rome What Lola said. However, if you really want to do it, it is possible. Leave Firenze S.M.N. on a Regional train (no reservations offered or possible) at 00:38 to Pisa Centrale arriving at 01:59. Wait 26 minutes for the train from Torino to Salerno and depart at 02:25. It is an InterCityNight so it is subject to compulsory reservation, 2nd class only seated accommodation, but with Sleeping-car and Couchettes, for arrival in Roma Ostiense at 05:55. From there you can get a bus or tram; or walk the covered walkway to Piramide for the Metro. I'm not sure what time they start running, and a lot will depend on the day of the week. Dan, have you planned to avoid the days that various sights are closed in the various cities you are going to, for example Mondays in Rome and Tuesdays in Napoli? Various days in Firenze depending on what you want to see?
